Around 10 years ago, I had a problem with a Seagate hard drive installed in a fancy university networked computer I was using at home. It was a long bank holiday. Usually, I pull rank over stuff like this and either get the Uni IT experts out to my home or speak to them on the phone, but I was unable to contact them for various reasons.
I knew I'd seen details of a freephone international phone number to contact Seagate somewhere and on further research, the number I found was very similar to the one posted by tollview. I rang them with some trepidation and ended up talking to an American in California for about 30 minutes or so. He solved the problem for me but it caused me to check my phone bill for the next month almost daily to see if the call charge had appeared. It turned out to be toll-free even from the UK.
Nowadays, Seagate appear to run something similar via a UK freephone number:

The initial digits of the phone number correspond with the UK 0800 freephone access code yet the call is most definitely diverted to the USA - I've rang it to check. It seems anything is possible as long as someone is prepared to pick up the cost of the call.
The best advice though tollview is to check the matter out with your telephone provider.
